Secure Vehicle Module Pairing via Wired Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing short range wireless communication systems in vehicles are vulnerable to malicious attacks due to the transmission of pairing data wirelessly, which can lead to issues during the pairing process, and may not utilize the full potential of wired connections for data transfer.
Innovation Solution
Conveying pairing data via a wired connection to establish a secure short range wireless communication (SRWC) connection between vehicle modules, ensuring that the pairing data is validated and used to initiate a wireless connection, thereby enhancing security and potentially improving data transfer speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pairing data is transmitted wirelessly during the pairing process, then the pairing process can be completed, but the system becomes vulnerable to malicious attacks and security breaches
Solution Approach 1:
The patent introduces a wired connection as an intermediary medium for transmitting pairing data between vehicle modules. Instead of directly transmitting sensitive pairing data wirelessly, the system uses a physical wired connection (such as USB or other data cables) as a secure intermediary channel. This wired intermediary ensures that pairing data cannot be intercepted by wireless malicious attacks, while still enabling the pairing process to be completed successfully.
2Productivity
If pairing data is transmitted wirelessly, then the pairing process can proceed, but data transfer security is compromised
Solution Approach 1:
The patent applies preliminary action by establishing a secure wired connection for pairing data transmission before any wireless communication is initiated. The system first uses the wired connection to exchange pairing information and establish trust relationships, ensuring security is already in place before wireless data transfer begins. This preliminary secure setup prevents subsequent wireless attacks on the pairing process.
3Reliability
If wired connections are used for pairing data transfer, then security is enhanced, but the potential speed advantage of wireless communication is not fully utilized
Solution Approach 1:
The patent segments the data transfer process into two distinct phases: a secure pairing phase using wired connection, and a high-speed data transfer phase using wireless communication. The wired connection is used only for the critical pairing data exchange that requires security, while the subsequent bulk data transfer utilizes the faster wireless channel. This segmentation allows the system to optimize for security where needed and speed where appropriate.
Data Source
AI summary
A system and a method for establishing short range wireless communication between two vehicle modules. The system determines the availability of a first vehicle module and a second vehicle module to establish a short range wireless communication connection. The determination may be based upon whether the first vehicle module is storing pairing data. The system validates the pairing data at the second vehicle module using a wired connection. If the pairing data is validated, the first and second vehicle modules may establish a wireless connection using at least a portion of the pairing data. When the wireless connection ends, the system may re-determine the availability and revalidate any pairing data via the wired connection before establishing a wireless connection.
